I have an ARM version of the t3-nano. The T3000 software can access it using the RS485 port and allows me to work with it. I have updated the firmware to the latest revision. I am using static IP’s. My PC and the Nano are on the same subnet etc and the nano does respond to a ping, however when I scan for it using the t3000 software the ethernet scan increments the found devices count, indicates a reply:0 and hangs.
I had the identical issue with a T3-TB16. The good news is that the issue appears to be related to using the 10.0.0.x subnet. Using a different subnet eliminated the problem.
The Windows network may be set as “Public,” which blocks UDP broadcast packets used by BACnet/IP on port 47808. The subnet mask between the PC and the controller might not match. It’s also possible that the Windows firewall or third-party security software is blocking UDP broadcasts on the 10.x network.
You can change the Windows network type to “Private.” Allow UDP 47808 (BACnet/IP) and TCP 502 (Modbus/TCP) through the firewall. Make sure the IP address and subnet mask match on both the PC and the controller.
